Gypsum is calcium sulfate (CaSO4). Refined gypsum in the anhydrite form (no water) is percent calcium (Ca) and percent sulfur (S). Usually, gypsum has water associated in the molecular structure (CaSO4·2H2O) and is approximately percent Ca and percent S (plaster of paris). Gypsum fertilizer usually has other impurities so grades are approximately 22 percent Ca and 17 ...

FGD Gypsum Introduction

The term "synthetic gypsum" has been used widely to encompass materials produced by a variety of industrial processes. In addition to FGD gypsum, synthetic gypsum includes materials such as phosphogypsum, (a byproduct of processing phosphate ore to make phosphoric acid), Titanogypsum (a byproduct from the production of titanium dioxide), fluorogypsum (a byproduct from the production of ...

What is the purpose of adding gypsum in cement?

Gypsum is a mineral and is hydrated calcium sulfate in chemical form. Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process.
